Scheduling Methods for Lot Processes in JIT Production System

This paper deals with scheduling methods in a JIT production that includes lot processes. In general, the delayes often occurred in multivolume JIT production systems that include lot processes, because set-up time is increased in the multivolume JIT production. To cope with this difficulty, we propose three scheduling methods to decrease delays and work-in-process inventory in lot processes. Furthermore, we evaluated the methods by numerical experiments.
